INK-BOTTLE STOPPER.

Specification of Letters Patent.

Patented Aug. 26, 1919.

Application filed February 9. 1918. Serial No. 216,154.

`ments in Ink-Bottle Stoppers, of which the following is ,a specification.

My invention relates to a valvular pourout bottle closure of the type which serves not only as a means for sealing the bottle when not in use, but also serves to constitute a means for delivering a stream of liquid from the bottle while permitting a' free flow of air into the bottle to take the place of the displaced liquid. The invention in the form selected for illustration relates to such a. pour-out closure for use particularly on ink bottles and other receptacles in which it is desired to shut ofl` the air inlet when not in pouring position and which can be readily manipulated to move the saine into position to insure the quiet flow of a small stream therefrom.

In such devices'it is essential. for reasons of economy, that such.closures be designed so that they may be constructed by simple molding operations in large quantities with a minimum amount of labor and material and so that they may be assembled with the least expenditure of manual labor.

Accordingly one object of the invention is to provide a construction peculiarly sus- Iceptible to have its parts constructed of molded material and designed so that the manufacturingsteps may be simple straightline die operations.

It. is also necessary that the parts be constructed in/such a way that there will be a hern'ietically sealed closure when the movable valveelement of the device is in closed vposition and which, at the same time, will permit a free and easy operated actuation of the movable valve element. 0 It is ,quite usual where a number of ink wells are filled each morning for the operaceiving receptacle thereby to minimize spilling which is usual with the old curved Y stream pour outs when they are carelessly tipped into pouring position over the receiving i'eceptacle.

A further object of thc invention is to provide a simple form of construction designedv .so that when the bottle is reverted into ilpriglit positionthe stream will be promptly, positively and sharply cut ofi' and which will automatically slick back into the bottle any drip from the cut off stream.

Various other objects and advantages of the invention will be in part obvious from an inspection of the accompanyingI drawings and in part will be more fully set fortlrin the following particular description vot one form of mechanism embodying my inventioii, and the invention also consists in ce1'- tain new and novel features of construction and combination of parts hereinafter set forth and claimed;

I iil the accompanying drawings Figure 1 is a lvertical sectional view taken axially through a preferred embodiment of my invention shown attached to the upper Fig. 3 is a plan view looking down upon' the device shown in Fig. 1;

Figs. 4 and 5 are respectively a vertical sectional view and a plan view ofthe linderside ofthe retaining ring shown in Fig. 1 :l

Figs. 6 and 7 are respectively a vertical sectional view and a plan view of the nozzle seat: and,

Fig. 8 is a front view of the nozzle shown in Fig. 1 and detached from its cordinated parts.

The closure constituting the subject-inatter of this invention is designed as an article of manufacture for attachment to any kind of a bottle or other receptacle of suitable size. and is arranged 'to be placed on top of the bottle and fastened thereto by any conventional ferrule fastening device. The upper portion of such a bottle is shown at 10 in Fig. 1, positioned on top of which a cork ring washer 11' constituting a cushioning device between the attachment and the bottle to prevent breakage when the paits are assembled in a capping machine. The washer fis designed to be placed under sutlicient pressure to form a tight seal between the attachment and the bottle. A flat relatively bottle. For instance, when the device is used as' an ink bottle the air, passageway is coated with a thin! coating of grease.

The device as thus described Aconstitutes a single unit usually Asold with a rmetal ferrulel 46 b can be a Xed .to the bottlel as is usual with such devices. In assembling the parts,. the nozzle with the asket forced 'into position on the lugs 25 9.11526 is dropped through the yretaining ring u'ntil the shoulder 30 entional engagement of the arts can be relied upon to temporarily holl the parts in position suitable for packin and shipping. The device is afiixed to the lottle by any of the suitable capping machines but in assembling these devices extreme care need not be exercised, for any excessive pressure on the retaining ring will merely act to compress the' cork washer and will have no binding effect on the gasket after it has been compressed to its desired prefixed thickness.

With the nozzle rotated into its closed position, that is, with the passageways` in the nozzle disalined from the openings through the nozzle seat, the bottle will be effectively sealed and no liquid can pass. therefrom or air pass into the receptacle thus closed.

In operat-ion, the operator engages the finger piece b v rotating the nozzle from the indicated closed to the indicated open position,.the passageways are moved into alinement with the openings in the nozzle seat and the bottle can then be tipped into pouring position. Instead of gradually and cautiously tipping the bottle, it can' be quickly turned fully into a horizontal position without fear of misdirecting the direction of flow of the stream for it will then be straight down from-itl'ie pouring mouth. The liquid will pass without obstruction 'directly through the liquid conduit and will issue from the discharge portion thereof in the form of an easily moving pencil of liquid which will fall vertically and without the outward curve characterizing similar` pouring devices now known. During this fiow air can freely enter the air conducting passageway and will pass into the bottle scouring the passageway or the opening of any particle of liquid or other obstacle which may have collected in the air conduit.

As the bottle is moved back into its vertical position, the sharp pouring lip will promptly and positively cut ofil the stream without any resulting drip to trickle down the front of the bottle. The movement of the liquid remaining in the long liquid remeans of which the attachment' ceiving passageway, appears to exert a suction effect `upon therelatively small body of liquid in the discharge passageway, drawing n the saine back from the pouringlip and re-` turning 'the surplus li uid fback v'into the bottle'. The nozzle can t en be rotated into closed position and the closurey will' then; be

free of'any liquid adhering\'to the "rim,

-Coatlng theair inlet passageway with -a substance which has little adherence. to the liquid will prevent 'the'.liquid adhering to the n'iaterial of which'the closure maybe constructed, thus eliminating those obstruc- `tions at this place which are apt toV charac-4 terize devices where the air inlets arevof relatively small cross-section.'-

, The nozzle, its seatvand the retaining ring are made of a hard rubber composition which can be readily molded to shape'and which, whenl finished, will` insure a close 'ation may be made `by those skilled in the art without departing from the spirit of the invention.
